LoosE-Lr BINDER nun Hanna 1 e Application filed may -5,

To all whom it may concern Be it known that I, Enmas'r P. WoLr,

a citizen of the United States, residing at. -New York, in the count pf New York and State of New York, ave invented new and useful Im rovements in Loose-Leaf Binders and, Fil ers Therefor, of which the following is a specification.

This invention relates to loose leaf binders and fillers therefor, and one of the principal objects is to produce a binder in which the fly-strips shall be so connected to the covers that they ma not easily be torn 01f.

Another 0 ject is to produce a device of this nature havin a metallic fly strip;

Another object 18 to produce a, filler which. may be self binding for the purpose of filing away the contents after the binder proper is filled.

Another object is to produce a' binder and filler of simple construction, cheap to manufacture, and efficient in operation.

With these and other objects in view, the invention resides in certain novel construction and combination and arrangementof parts, the essential features of which are hereinafter fully described, are

ointed out in the appended claims, and are illustrated in the accompanying drawing, in which Figure 1 is a pers ective view of my improved binder and fi er.

Figure 2 is a perspective view of my 1mproved binder and filler showing the several parts in somewhat disconnected position, parts being broken .away for the sake of clearness. Figure 3 is a transverse sectional view of the same. Figure 4 is a detail view of the filler holding device.

igure 5 is a perspective view of the filler per se. a

Like characters'of reference refer to like parts in all views.

Referring to the drawing in detail, 10 represents the boards of the covers, and 11 the outside covering which ma be of fabric or other desired material an across both boards 10 and an intervening space for the back as is usual, the edges bein folded inside and pasted down and finis ed b the usual sheet 12.

fabric extending from one board to the other across; the back of the binder, but

proved unsatisfactory as'they these have may easily e. torn ofi', and ofi'er no great amount of reinforcement to the back. The

present fly strips are of metal and are constructed as follows z- Each of the fly strips comprises a U- shaped-hinge member '13 which straddles the rear edge of the board and. is secured thereto by punching or extruding some portion into the board. The front fly strip is; indicated at 14 and is hingedly connected to its' respective member 13. The member 14 is provided with a longitudinal channel 15 to which may be pivotally secured clips 16. The rear member or fly strip is indicated at 17 and is hingedly secured to its respective member 13 and is doubled upon itself as at 18 the upper fold being formed with notches 19.

A strip of fabric 11 passes from board to 'board across the insideof the back and bemetal strip 23 has secured at each end a flex- When'the filler is placed in the cover mem- 100 bar 23 it is positioned between the folds 18 wlth the members 24 extending upwardly through the notches 19. The member 25 is removed and the ends of the members 24 are placed upwardly through the pivot eyelets of the clasps or clips 16. The members 25 are now threaded over the flexible tongues 24 and the latter are bent to place and then the clips 16 are moved home soas to hold the elements 25 and 24 firmly in the channel 15. When the filler is to be removed to be filed away or stored, the same is removed from the binder and an element 29 which is normally folded in rear of the member 22 is now folded around the back of the papers 21 and the ends of members 24 are threaded through punchings in the member 29. A cover sheet is then threaded on the members 2 .1, and members 25 are again placed in position on the members 24, members 2% are bent parallel with members 25, and slides 27 are moved to hold the members 24 in their adjusted position.

While the filler is in the binder proper, the back sheet 22 is slipped into the pocket 20 giving a neat finish and holding the element 29 down and concealed.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims.

' weaves What is claimed as new is l. A device of the class described com- 1 prising a pair of cover boards,- a folded fiy and slide clips on one of said pair of strips and co-operative with said tongues.

2. A. filler including a rear cover sheet formed with a portion normally lying'parallel with the paper of the filler andmovable to a position to form a back for binding. 3. A filler including a rear cover sheet formed with a portion normally lying parallel with the paper of the filler and movable to a position to form a back for binding, and a paper clip for holding said cover sheet in either position.

lln testimony whereof I have aflixed my signature.
